Intel® Optimized Cloud Modules for Terraform

© Copyright 2024, Intel Corporation

Terraform Intel Azure VM - Linux VM

This module creates an Azure virtual machine on Intel Icelake (for Intel Non-TDX VMs) and Sapphire Rapids CPUs (for Intel Confidential Compute VMs with Intel TDX) on Linux Operating System. The virtual machine is created on an Intel Icelake Standard_D2_v5 by default and if using Intel Confidential Computing VMs with Intel TDX the default will be Intel Sapphire Rapids Standard_DC2es_v5.

As you configure your application's environment, choose the configurations for your infrastructure that matches your application's requirements.

In this example, the virtual machine is using a preconfigured network interface, subnet, and resource group. The tags Name, Owner and Duration are added to the virtual machine when it is created.

We have now included example for provisioning Intel Confidential VMs with TDX- see "azure-linux-tdx-vm" and "azure-rhel-tdxvm" example folders.

Usage

See examples folder for code ./examples/azure-linux-vm-spot-vm/main.tf

Example of main.tf

# Example of how to pass variable for virtual machine password:
# terraform apply -var="admin_password=..."
# Environment variables can also be used https://www.terraform.io/language/values/variables#environment-variables

Provision Intel Cloud Optimization Module

variables.tf

variable "admin_password" {
  type        = string
  default     = null
  sensitive   = true
}

main.tf

module "azurerm_linux_virtual_machine" {
  source                              = "intel/azure-linux-vm/intel"

  source_image_reference = {
    "offer"     = "RHEL"
    "sku"       = "8-LVM-gen2"
    "publisher" = "RedHat"
    "version"   = "latest"
  }
  tags = {
    "owner"    = "[email protected]"
    "duration" = "1"
  }
}

Run Terraform

terraform init  
terraform plan
terraform apply

Note that this example may create resources. Run terraform destroy when you don't need these resources anymore.

Considerations

When admin_password is specified disable_password_authentication must be set to false.

Either admin_password or admin_ssh_key must be specified.

The virtual machine is using a preconfigured network interface, subnet, and resource group.

To use the Intel Confidential VMs with TDX see the "azure-linux-tdx-vm" example.
